You can disassemble the ROMs but of course the comments are missing. Nonpareil allows to trace the code together with the registers. That helps a lot understanding the code. Analyzing SOLVE and \(\int_y^x\) would be interesting as well though I assume it's similar to the code in the Advantage module.

Well similar for sure, but not quite the same I assume due to the memory map and registers? The Advantage's implementation uses wonderful trickery with buffer #14 and SILOOP and SIRTN, probably to overcome some alleged earlier design deficiencies (the 15C was released later on).
